Although the War is now over, tensions run high as Aang and Zuko are put on a "collision course" after the Avatar travels to a Fire Nation colony and finds "tension between neighbors" -- a threat that may "shatter the world's newfound peace". The unfinished conversation between Zuko and Ozai about the whereabouts of Ursa, Zuko's long lost mother is completed, but the conversation takes a different path after Zuko asks the question and her fate still remains unknown. Negotiations with Earth King Kuei and the beginning of the Harmony Restoration Movement commence.
